Solution Overview
Problem
Debris in wellbore fluid can contaminate auto-fill equipment and impede operations in subterranean well systems, leading to increased costs and operational challenges due to the need for surface-mounted hydraulic pumps and potential bridging issues during cementing processes.
Innovation Solution
A modular debris separator device composed of interchangeable components, such as plates, screens, weirs, and impellers, that can be customized and assembled in various configurations to effectively separate debris from wellbore fluid, preventing contamination and bridging by utilizing angularly offset pass-through areas, longitudinal screens, and tortuous fluid paths.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If debris is not separated from wellbore fluid, then auto-fill equipment performance deteriorates and operational costs increase, but implementing debris separation requires additional downhole components and system complexity
Solution Approach 1:
The debris separator is divided into multiple modular components including screens, weirs, and impellers that can be independently assembled and configured. Each component performs a specific function in the debris separation process, allowing the system to be customized based on operational needs while maintaining overall reliability.
Solution Approach 2:
The debris separator assembly is designed to perform multiple functions within a single downhole tool: debris separation, fluid flow management, and protection of auto-fill equipment. The modular components can be configured to address different debris sizes and flow conditions, providing universal applicability across various wellbore operations.
2Productivity
If surface-mounted hydraulic pumps are used to fill tubulars, then filling capability is maintained, but operational costs and time requirements increase
Solution Approach 1:
The debris separator enables auto-fill operations by allowing wellbore fluid to automatically enter and fill the tubulars through the debris separation process. The system uses the natural flow of wellbore fluid and gravitational forces to drive the filling operation without requiring external hydraulic pumps, thereby eliminating the time loss and operational costs associated with surface-mounted pumping equipment.
3Device complexity
If debris is allowed to pass through auto-fill equipment, then equipment simplicity is maintained, but debris accumulates and forms masses that impede subsequent operations
Solution Approach 1:
The debris separator extracts and removes debris from the wellbore fluid stream before the fluid enters the tubulars. Screens capture particulate matter, weirs separate heavier debris through gravitational settling, and impellers enhance separation by creating centrifugal forces. This extraction process prevents debris accumulation and bridging in subsequent operations while maintaining relative system simplicity.
4Adaptability or versatility
If modular debris separator components are assembled in various configurations, then adaptability to different debris types is improved, but assembly complexity and installation time increase
Solution Approach 1:
The debris separator employs segmented modular components that can be independently selected and assembled based on the specific debris characteristics and operational requirements. Each module (screens, weirs, impellers) can be configured in different arrangements to optimize performance for different debris sizes and types, providing adaptability while maintaining standardized connection interfaces for ease of assembly.
